Write prompts that reduce hallucinations and get precise code on the first try
Stop debugging AI-generated code that ignores your constraints. Get prompts with context, types, error handling, and test requirements built in.
Fewer hallucinations
Context-first prompts vs bare instructions
Fewer tokens used
Precise prompts reduce back-and-forth
Iterations to working code
Structured prompts vs vague requests

Same task, same AI model. The only difference is the prompt.
“help me write a function to sort users”
function sortUsers(users, field) {
return users.sort((a, b) => {
if (a[field] > b[field]) return 1;
if (a[field] < b[field]) return -1;
return 0;
});
}
// Usage
const sorted = sortUsers(data, "name");Structured prompt with context & constraints
function sortUsers(
users: User[],
sortBy: SortField,
direction: 'asc' | 'desc' = 'asc'
): User[] {
const planOrder = { free: 0, pro: 1, enterprise: 2 };
return [...users].sort((a, b) => {
const va = a[sortBy], vb = b[sortBy];
if (va == null) return 1;
if (vb == null) return -1;
let result: number;
if (sortBy === 'plan') {
result = planOrder[va] - planOrder[vb];
} else if (sortBy === 'createdAt') {
result = Date.parse(va) - Date.parse(vb);
} else {
result = String(va).localeCompare(String(vb));
}
return direction === 'desc' ? -result : result;
});
}- No type safety — untyped parameters and return value
- Mutates original array with .sort() instead of copy
- No sort direction — always ascending
- Crashes on null or undefined field values
- Full TypeScript with User[] and SortField types
- Immutable — spreads array before sorting
- Custom enum ordering for plan tiers
- Null-safe with consistent null placement

Your one-liner becomes a structured prompt with context, types, constraints, and test requirements.

For developers
Context-first prompt structure
Rephrase structures every code prompt with context first, so the AI understands your codebase before generating.
Your existing code, stack, and patterns
TypeScript + React + TanStack Table
The specific objective
Sort users by multiple criteria
Error handling, types, tests, conventions
No mutation, throw on invalid input

Frequently Asked Questions
Rephrase adds explicit context to your prompts: existing code patterns, type definitions, framework versions, and constraints. When an AI model knows your exact stack and requirements, it hallucinates less because it has concrete boundaries instead of guessing.
